This boo is devoted to the advanced stages of mechanical drawing only and does not treat of the funda- mental principle, such as the proper methods of handling the in- struments, etc. nor does it treat of design, it being preliminary to this subject. It consists principally of a series of progressive notes which are calculated to impart a wor ing nowledge of the principles of graphic representation and at the same time a number of e amples are offered which will ac uaint the student with the conventions of the art. Part I is intended for the freshman year and contains three chapters on the following subjects: Isometric drawing, cavalier projection, shadows and perspective drawing. Part II is intended for the sophomore year and is to be used in con- nection with the class room and lecture wor in descriptive geom- etry. It contains two chapters which treat of theoretical and prac- tical problems in both plane and perspective drawing, such as developments, practical perspective, lettering, etc. The discussions are brief and clearly written, and the illustrations throughout are e cellent. The wor no doubt will be of great value when used, as Intended, in class room wor . TR D C T GU . The Ganz ystem of lectric Traction.

R. enderson s article on ocomo- tive peration in your ept. number, we do not uite understand his statement in regard to the cost of general repairs. e gives the impression that the cost of general repairs would average about one cent per mile. The cost for locomotive repairs on various railroads is as follows: Per mile. Pennsylvania Railroad. 1903 7.74 cts.
